No offence OP, just to warn any potential buyers....Evolve tested this on the dyno and it made zero power or torque gains.

None Taken!

This I'd suggest is designed not only as rather tasty piece of eye candy but also for improved throttle response...... When I fitted a Dual Cone Intake system to my new 335i it didn't allow the engine to produce more power but it did allow the Turbo’s to spool up quicker - this I believe (maybe the placebo effect) does improve throttle response!
